vHARIVIONICA WITH BELL OWS.

Application led April 25, 1921.

To all 207mm t may concern.'

Be 1t known that I, JEROME BAR'roLowsiir,

la citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Harmonicas with Bellows, of which the following is a specification.

My invention is a harmonica accordion in which one or more harmonicas are played by an accordion mechanism.

Referring to; the drawing in which my invention is illustrated and which forms a part of this specification.

Figure 1 is a perspective view of my invention taken from above the same.

Figure 2 is a plan view of my invention.

Figure 3 is a cross section of my invention taken on line 3*3 of Figure 1.

Figure 4 is a fragmentary cross sectional view of one of the harmonica holders with the closing plate in close position.

In the drawing 1 indicates an accordion casing. Said casing is provided in its upper or front wall 2 near the rear edge thereof with two longitudinal grooves 3 and 4. In said grooves are harmonica mounts 5 and 6, each of which comprises a pair of upstanding walls 7 and 8, which rest against the sides of the grooves and are adapted to grip the harmonica.

The wall 2 has a series of ports 11 extending therethrough into the groove 3 and a series of ports 12 extending through into the groove 4. Harmonicas 13 and 14 are introduced between and gripped by the walls 7 and 8 within the mounts 5 and 6 respectively with the mouth openings of said harmonicas adjusted in registration with the ports 11 and 12 respectively. lVithin the casing 1 is formed an air chamber 15 with which the inner ends of the ports 11 and 12 communicate. Valves 16 and 17 control the inner ends of the ports 11 and 12, the stems 18 and 19 of said valves extending through the opposite wall of the chamber 15. there being packings 15) and 20 in said wall around said valve stems. valves of each pair of ports 11 and 12 which are arranged opposite each; other are connected outside the wall of chamber 15 to a valve lever 21 which is pivoted at 22 within the casing 1. A spring 23 secured to the inside of the casing 1 engages each valve lever 21 and holds the valves 16 and 17 in closed position, closing the ports 11 and l2.

The ends of the stems of the Serial No. 464,263.

To each lever 21 is connected a key rod 24 which extends through the wall 2, on the outer end of which rod is secured a key button 25 which partly rests and operates within a recess 26 in the outer side of said wall. The keys 25 arearranged alternately in two longitudinal rows forwardly of the mount 6. Rabbets 27 and 28 are undercut in the outside of wall 2, the rabbet 27 being cut forwardly from the inner wall of groove 4, and the rabbet 28 being cut forwardly from the outer edge of rabbet 27. A plate 30 is formed with a ange 31 on its inner edge, the main portion of said plate resting in rabbet 28 and the flange 31 resting in the rabbet 27. The inner edge of the plate 30 forms the main portion of 4 and the mount wall 8. Pins 32 project from the outside of the plate 30 at the ends thereof by means of which the plate may be moved through the wall 8 of mount 6 to cover the ports 12. The edges of the plate 30 and fiange 31 are beveled to engage the undercut edges of the recesses 27 and 28 to prevent the plate from falling out of said recesses. By means of the plate 30 the openings 12 may be closed so that only one harmonica may be played.

A bead 33 projects from the front side of the wall 2 along the forward side edge thereof and a strap 34 is secured at its ends on the outside ofv said bead under which strap the performers right hand is placed so that his fingers may depress the keys 25. A bellows 35 is secured to the inner wall 36 of the casing 1, an air tube 37 leading from said bellows into the air chamber 15. A strap 38.is secured at its ends to outer movable wall of said bellows under which strap the performers left hand is placed to hold the instrument.

By depressing the keys 25 the levers 21 are operated and the valves 16 and 17 opened so that air from chamber 15 may pass through ports 11 and 12 into the mouth openings of the harmonicas to play the harmonicas. While I have shown two rows of ports 11 and 12 for two harmonicas respectively, it is obvious that only one or more than two rows may be used for one or more than two harmonicas respectively.

Having described my invention, I cla-im:

1. A musical instrument including a casing provided with a row of ports, a harmonica, a mount for the harmonica with its mouth openings in .register with said ports` one side of groove" an air chamber in said casingwith which said ports communicate, valves controlling said ports, keys on said casing for operating said valves, a bellows on said casing, and a tube leading from said bellows into said air 3. A musical instrument including a casing provided with a groove in its outer wall and a series of ports in said wall leading into said groove, a slidable plate in said wall forming one side of said groove, a harmonica, a pair of walls upstanding in said groove at the sides thereof respectively, for gripping a harmonica with its mouth openings in communication with said ports, an air chamber in said casingwith which said ports communicate, valves controlling said ports, keys on said casing for operating said valves, a bellows on said casing, and a tube leading 'from said bellows into said air chamber.

In testimony whereof I aHiX my signature.

JEROME BARTOLOWSKY.
